Laser beam analyzers are used to determine the quality of a laser beam

Beam expanders are optical lens assemblies that are used to increase the diameter of a laser beam or other light beam

Excimer lasers are rare-gas halide or rare-gas metal vapor lasers that produce relatively wide beams of ultraviolet laser light.

Diode lasers use light-emitting diodes to produce stimulated emissions in the form of coherent light output.

Helium neon (HeNe) lasers have an emission that is determined by neon atoms by virtue of a resonant transfer of excitation of helium.

Solid state lasers use a transparent substance (crystalline or glass) as the active medium, doped to provide the energy states necessary for lasing.

Ion lasers function by stimulating the emission of radiation between two levels of an ionized gas.
